For Jake it makes the most sense, as the car's condition is near perfect and for him to drop an engine in it will be a lot cheaper than you or me. Plus he might even be able to write it off as a test car or something. Its almost a no brainer. Almost all salvaged porsches have been wrecked and most likey have frame damage and costly body/headlight damage. If I was a mechanic I would consider something like this a gift, as half the cost of an engine swap for us is in labor and with jakes engines, Well I am sure he would cut himself one heck of a discount and labor is negligible
For someone like me, I could probably get an engine (regular not modded) for around 5 to 7 grand, then pay somebody to put it in. Not that great of a deal for me.
